Tx22v2 Transmitter
User Information
Tx22v2 is a hand-held wireless transmitter intended to control up to 12 model railway trains. It
has controls for Speed, Direction, Inertia, Lights and Loco selection. Tx22v2 is available in 2
versions: with and without a detent on the throttle control:
•
the detent version has a mechanical 'click' at the centre of the travel and is intended
for use with DT receivers configured for fwd/rev control on the throttle channel,
•
the no-detent version is for use with receivers configured for full-range throttle and
separate direction switch. When the Tx22v2 toggle switch is not used for direction, it
is available for controlling auxiliary functions such as LED lights and sound modules.
Technology
•
Tx22v2 uses the 2.4GHz band which requires no frequency channel control and is very resilient against interference.
All radio frequency components are contained on the internal Tx2 module. There are no user adjustable parts on this
module and it should not be modified.
•
Tx22v2 is compatible with all DSM2 receivers. This includes all Deltang receivers.
•
Any number of receivers can be bound to your Tx22v2 but only up to twelve, bound to different Selecta positions,
should normally be switched on at a time to operate them independently. An exception to this rule is multi-headed
trains – Deltang receivers support features (which required programming setup) to match the speed of separate locos
in a multi-headed consist.
•
Range is suitable for indoors and small outdoor sites; the outdoor free-air range to a Deltang receiver is at least 50m.
Range indoors is affected by building construction materials, furniture, people and receiver installation.
•
Knob and switch positions are transmitted as separate 'channels' (1-7) which must match the receiver configuration:
throttle:
channel 1
selecta:
channel 2
toggle switch:
channel 3 (up or forward = channel high, down or reverse= channel low)
inertia:
internal use or channel 4 or channel 5 (configurable)
bind button:
channel 5 (none if inertia configured as channel 5) (up = channel high, down = channel low)
Battery
•
Tx22v2 uses a PP3 9V battery, Alkaline, LiIon or NiMH The maximum
working voltage of the internal Tx2 module is 10V and there is a protection
diode wired in series with the battery negative lead. This allows the battery
voltage to be up to 10.7V. If the battery voltage is above this value, the
internal regulator will shut down and the transmitter will not operate.
•
Remove the sliding lid at the bottom rear of the case to insert or replace the
battery. The image shows the orientation. The battery is held in place with a
piece of foam tape attached to the battery compartment lid.
•
Make sure that the power on/off button is off (up) before) adding or removing
a battery.
•
The connector will only clip onto the battery one way. TAKE CARE, if force is needed, the connector is probably the
wrong way round.
On / Off Push Button
•
Tx22v2 has an illuminated push-button on/off switch. It is best to switch the transmitter on before the receiver.
•
The LED flickers slightly while an Inertia transition is in progress.
•
The LED flashes more boldly when Binding.
